HS 290379 Other

Quick Answer: HS code 2903.79, "Other," covers a diverse range of acyclic halogenated derivatives of hydrocarbons not specifically classified elsewhere within heading 2903. This includes various complex organic chemicals containing halogens (fluorine, chlorine, bromine, iodine) and lacking a cyclic structure. Due to its "other" nature, specific product classification requires careful analysis of chemical structure. Duty rates vary significantly by jurisdiction and specific product. For example, the UK Trade Tariff shows rates like 4.00% and 0.00%, while the EU TARIC lists 5.50% and 0.00%. The US Harmonized Tariff Schedule (HTS) includes rates such as 3.7% ad valorem, with many products eligible for "Free" duty under various preferential trade agreements (e.g., A, AU, CL). However, certain specific products within this "other" category may face higher rates, such as 25% in the US, often linked to specific trade measures. Importers and customs brokers must precisely identify the chemical compound to determine the correct subheading and applicable duty.

How to Classify This HS Code?

What products does HS 290379 cover?

This subheading covers acyclic hydrocarbons, halogenated only with fluorine, bromine, or iodine, that are not specifically provided for in other subheadings under Heading 2903, nor are they mixtures of two or more such compounds. This includes a diverse range of single, distinct perhalogenated or partially halogenated acyclic hydrocarbons where the halogen atoms are exclusively fluorine, bromine, or iodine, and which are not chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or hydrofluorocarbons (HFCs) of subheadings 2903.71 through 2903.78. The WCO Harmonized System Explanatory Notes for Heading 2903 clarify the scope for halogenated derivatives of hydrocarbons, emphasizing the specific halogenation requirements for this particular "other" category, as reflected in the USITC Harmonized Tariff Schedule (HTS) and EU TARIC classifications.

What falls outside HS 290379?

The following products are excluded from HS 290379: acyclic hydrocarbons halogenated with chlorine, even if also halogenated with fluorine, bromine, or iodine, which would typically fall under subheadings 2903.11 through 2903.69, or specifically under 2903.71 to 2903.78 if they are CFCs, HCFCs, or HFCs. For instance, 1,1,1,2-Tetrafluoroethane (HFC-134a) is classified under 2903.79.10, not 2903.79, because it is a specific HFC. Similarly, mixtures of two or more different acyclic perhalogenated or partially halogenated hydrocarbons are excluded and are generally classified under 3824.71 through 3824.79, depending on their ozone-depleting potential, as per Chapter 38 notes and specific subheading provisions for mixtures of halogenated derivatives.

What are common classification mistakes for HS 290379?

A common error is misclassifying mixtures of two or more different halogenated acyclic hydrocarbons into 2903.79. This subheading is strictly for single, distinct chemical compounds, not mixtures. Importers often overlook the specific provisions for mixtures in Chapter 38, particularly subheadings 3824.71 through 3824.79, which are designed for preparations containing halogenated derivatives of acyclic hydrocarbons. Another frequent mistake involves incorrectly classifying compounds that contain chlorine in addition to fluorine, bromine, or iodine, as these would fall under other subheadings within Heading 2903, or even entirely different headings, depending on their specific chemical structure and function. Adherence to General Interpretive Rule (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes, is crucial to avoid these errors.

How should importers classify products under HS 290379?

The correct procedure for classifying products under HS 290379 involves a meticulous review of the chemical's precise molecular structure and composition. Importers and customs brokers must first confirm that the product is an acyclic hydrocarbon and that its halogenation is exclusively with fluorine, bromine, or iodine, with no presence of chlorine. Secondly, it is imperative to verify that the product is a single, distinct chemical compound and not a mixture of two or more such compounds, which would necessitate classification elsewhere, typically in Chapter 38. Consulting the WCO Harmonized System Explanatory Notes for Heading 2903 and cross-referencing with the USITC HTS or EU TARIC for specific national interpretations and rulings is essential to ensure accurate and compliant classification, thereby mitigating potential customs delays and penalties.

FAQ

What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2903.79 in the United States?

For products classified under Harmonized System (HS) subheading 2903.79 ('Halogenated derivatives of hydrocarbons; other'), the Most Favored Nation (MFN) duty rate in the United States is generally 4.0% ad valorem. This rate applies to imports from countries that do not have a specific free trade agreement or other preferential trade program with the U.S. that covers this product. Importers should always verify the current rates via the U.S. International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) for the most up-to-date information.

Are there any preferential duty rates available for HS 2903.79 under U.S. Free Trade Agreements?

Yes, many U.S. Free Trade Agreements (FTAs) offer preferential duty treatment, often resulting in a 'Free' (0.0% ad valorem) duty rate for eligible goods classified under HS 2903.79. Examples of countries whose originating goods may qualify for duty-free entry include Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG). To claim preferential duty, goods must meet the specific Rules of Origin outlined in the respective trade agreement, and proper documentation (e.g., a certificate of origin) must be provided to U.S. Customs and Border Protection (CBP) at the time of import.

What are the key classification criteria for products falling under HS 2903.79?

HS 2903.79 is a residual subheading for 'Other' halogenated derivatives of hydrocarbons, excluding those specifically enumerated in subheadings 2903.71 through 2903.78. Classification hinges on the chemical structure of the compound. Products must be organic chemical compounds containing only carbon and hydrogen atoms, with one or more hydrogen atoms replaced by halogen atoms (fluorine, chlorine, bromine, or iodine). The 'other' designation implies that the compound is not specifically listed elsewhere in the 2903.7 subheadings (e.g., 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), bromofluorocarbons (BFCs), or other hydrobromofluorocarbons (HBFCs)). Importers should have detailed chemical specifications, including CAS numbers and chemical names, to ensure accurate classification.

What documentation is typically required for importing goods under HS 2903.79, especially when claiming preferential duty rates?

Standard import documentation for HS 2903.79 includes a commercial invoice, packing list, and bill of lading or air waybill. When claiming preferential duty rates under a Free Trade Agreement, a valid Certificate of Origin or an equivalent declaration (e.g., a statement on the invoice) is mandatory. This document certifies that the goods meet the origin requirements of the specific FTA. Additionally, depending on the specific chemical compound, other government agency requirements may apply, such as those from the Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA) or the Montreal Protocol, which may require specific declarations or permits for certain halogenated hydrocarbons.

Are there any specific import restrictions or higher duties for HS 2903.79 in other major trading blocs like the EU or UK?

Yes, duty rates and potential restrictions can vary significantly across different customs territories. For instance, in the European Union (EU) TARIC system and the UK Trade Tariff, the MFN duty rate for HS 2903.79 is often 5.5% ad valorem, though this can vary by specific product and origin. Some specific halogenated hydrocarbons, particularly those that are ozone-depleting substances (ODS) or persistent organic pollutants (POPs), may face import prohibitions, quotas, or require specific licenses and permits under international agreements like the Montreal Protocol or the Stockholm Convention, which are implemented through national and regional regulations. Importers should consult the EU TARIC database or the UK Trade Tariff for the exact duty rates and any applicable import controls or licensing requirements based on the specific chemical and its origin.
